Update functions.php

- Type Determination: PHP 8.2's type determination features (int, string, void) were used. This makes the code more reliable.
- Abbreviated Logical Expressions: ?? With the operator, if a valid status code is not found for $code, a 500 error code is returned.
- Cleaner and Comprehensive Functions: Function names and logic are the same, but written in a more concise and effective way.
- Minify: The code was cleared of unnecessary spaces and lines, thus gaining a more compact structure.
